2.4 Monitoring Faults

Vocabulary

Outline

Devices that Monitor Faults

• geologists created instruments to record the ground movements along the fault
  • these instruments that geologists use measure the stress and deformation in the Earth's crust

• Creep Meter measures horizontal movements from the ground
  • this tool measures the amount of how much the fault has moved

• a tool using a laser to locate the smallest fault movements ever
  • can detect any movement of changes in the distance of the reflector

• this scale that measures the tilt of a fault
  • the Tiltmeter with with the water indicates how much the fault has tilted by the tilt of the water inside the scaled

• instead of making instruments that are based on the ground they also concentrated to measure ground movements from space
  • this type of a instrument uses radio waves to see how big the fault

• even if the geologist use all the technology in the world they still wouldn't predict the exact measurements of an earthquake
  • but geologists know that earthquakes store up energy inside a rock of a fault
    • geologist can also predict where the earthquake will strike by determining where faults are active
